Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to an automatic grinding machine that can detect the degree of grinding. Background Technology

[0002] A grinding machine is a device used for grinding and polishing product workpieces. It uses electric air compression to provide kinetic energy to drive sandpaper and other grinding equipment, making the surface layer of the product workpiece smooth, delicate or neat. Grinding machines are widely used in various processing and manufacturing processes, especially in the precision machining and surface polishing of the mold industry. It is a common alternative to pneumatic products.

[0003] In the prior art, such as the Chinese patent publication CN217678378U, a rail grinding machine for convenient measurement is disclosed. It includes a fixed base with two pairs of fixed bases arranged symmetrically on both sides of the rail joint. An annular guide rail is fixedly connected to the fixed base on the same side, and a guide rail slide is installed on the annular guide rail. A fixed frame is fixedly connected to the outer side of the guide rail slides on both sides, and a movable frame is provided on the outer side of the fixed frame. Telescopic measuring mechanisms are provided at both ends of the movable frame, and a grinding mechanism is provided in the middle of the movable frame. Through the telescopic measuring structure, the distance between the fixed frame and the normal rail surface can be measured, thereby measuring the grinding feed amount, which facilitates the measurement of the weld thickness at the joint. Through the grinding mechanism, the contact limit between the grinding mechanism and the normal rail surface via the two drive seats prevents excessive grinding, ensuring a smooth surface between the weld and the top surface of the rail after grinding, resulting in better processing accuracy. It eliminates the need for downtime measurement and is easy to operate.

[0004] In actual production, although this type of convenient rail grinding machine can also measure the workpiece being ground by measuring the distance between the fixed frame and the normal rail surface through the set telescopic measuring structure, thereby measuring the grinding feed and the weld thickness of the butt joint, this measurement method is not very direct. Further calculation is required to determine the amount of workpiece grinding thickness, resulting in poor performance of this device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an automatic grinding machine that can detect the degree of grinding, and has the effect of measuring the degree of grinding of workpieces and achieving excellent grinding results.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic grinding machine capable of detecting the degree of grinding, comprising a base box, a worktable fixedly connected to the upper surface of the base box, a motor box fixedly connected to the upper surface of the worktable, a grinding groove provided on the outside of the motor box, a vertical rod fixedly connected to the upper surface of the motor box, a top plate fixedly connected to the upper surface of the vertical rod, a cylinder fixedly connected to the bottom of the top plate, a disc provided on the outside of the top plate, the output end of the cylinder fixedly connected to the disc, a first motor fixedly connected to the bottom of the disc, a grinding head provided on the outside of the vertical rod, the output end of the first motor fixedly connected to the grinding head, a workpiece provided inside the grinding groove, a hydraulic tank fixedly connected to the upper surface of the worktable, a hydraulic hole provided inside the hydraulic tank, a rotating shaft rotatably connected to the outside of the grinding groove, a measuring ruler provided on the outside of the grinding groove, and the measuring ruler fixedly connected to the rotating shaft.

[0007] By adopting the above technical solution, after the worker places the workpiece inside the grinding groove, the first motor is started. The output end of the first motor drives the grinding head to rotate. Then, the cylinder is started. The output end of the cylinder drives the disc to move downward, causing the rotating grinding head to rotate and move downward as well. After the rotating grinding head contacts the workpiece, it begins to grind the workpiece. After grinding the workpiece, the worker pulls the measuring ruler and rotates it through the shaft until it is upright. Then, the worker directly measures the height of the workpiece after grinding through the upright measuring ruler to determine the degree of grinding. Through the above operation, the degree of grinding of the workpiece and the grinding effect are well measured.

[0008] A further feature of this invention is that a second motor is fixedly connected inside the motor housing, and a rotating hole is provided inside the motor housing. The second motor passes through the rotating hole and is fixedly connected to the grinding groove.

[0009] By adopting the above technical solution, the second motor is started, and the output end of the second motor drives the grinding groove to rotate.

[0012] A further feature of this invention is that a fan is fixedly connected to the outside of the disc, and the number of fans is two.

[0013] By adopting the above technical solution, two fans blow air to cool the working first motor and grinding head.

[0014] A further feature of this invention is that: a groove is provided inside the vertical rod, a guide rod is fixedly connected to the outside of the disc, a pulley is provided at the bottom of the guide rod, and the pulley is slidably connected to the groove.

[0015] By adopting the above technical solution, when the output end of the cylinder drives the disc to move downward, the guide rod is also forced to move downward. The disc moves smoothly through the sliding connection between the pulley and the slide groove, keeping the first motor in a vertical state.

[0016] A further feature of this invention is that a strong magnet sheet is fixedly connected inside the grinding groove, and the thickness of the strong magnet sheet is three centimeters.

[0017] By adopting the above technical solution, a three-centimeter-thick strong magnet sheet can firmly attract the workpiece to the inside of the grinding groove, making it easier to perform subsequent grinding on the workpiece.

[0018] A further feature of this invention is that: an arc-shaped groove is provided inside the grinding groove; a hydraulic press is fixedly connected inside the hydraulic tank; and the output end of the hydraulic press extends through the hydraulic hole and is fixedly connected to the arc-shaped groove.

[0019] By adopting the above technical solution, when the workpieces are of different sizes, the hydraulic press is started, and the output end of the hydraulic press drives the arc-shaped groove to move. After the arc-shaped groove contacts the workpiece, the workpiece is locked and fixed again by the combined action of grinding the groove wall and the arc-shaped groove.

[0020] A further feature of this invention is that the interior of the grinding groove is provided with cotton wool particles, and the spacing between each pair of cotton wool particles is equal.

[0022] A further feature of this invention is that the measuring ruler has an arc-shaped locking post on its exterior, and the worktable is fixedly connected to a clamp on its exterior.

[0023] By adopting the above technical solution, after the measuring ruler is rotated upright, the arc-shaped locking pin is moved to lock the measuring ruler in the clamp, which temporarily limits the measuring ruler and facilitates the subsequent measurement of the workpiece's grinding degree.

[0024] A further feature of this invention is that: the measuring ruler has a vernier groove inside, a vernier rod outside the measuring ruler, a slider at the bottom of the vernier rod, the slider being slidably connected to the vernier groove, and a pointer outside the slider.

[0025] By adopting the above technical solution, after the workpiece is ground, when the measuring ruler is vertical, the slider moves the vernier rod so that the bottom of the vernier rod contacts the upper surface of the ground workpiece, and then the scale corresponding to the pointer is read.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a base box, worktable, motor box, grinding groove, vertical rod, top plate, cylinder, disc, first motor, grinding head, workpiece, hydraulic tank, hydraulic hole, rotating shaft, and measuring ruler, allows the worker to place the workpiece inside the grinding groove and start the first motor. The output end of the first motor drives the grinding head to rotate. Then, the cylinder is started, and its output end drives the disc to move downwards, causing the rotating grinding head to rotate and move downwards as well. After the rotating grinding head contacts the workpiece, it begins to grind the workpiece. After grinding, the worker pulls the measuring ruler, which is rotated and uprighted by the rotating shaft.

[0028] 2. This utility model, through the arrangement of a second motor, rotating hole, reinforcing bracket, fan, slide groove, guide rod, pulley, strong magnet, arc-shaped slot, hydraulic press, cotton granules, arc-shaped locking post, clamp, vernier groove, vernier rod, slider, and pointer, starts the second motor. The output end of the second motor drives the grinding groove to rotate, and the rotating grinding groove drives the workpiece placed inside to rotate, so that the surface of the workpiece can be evenly ground during grinding. The cylinder machine generates a reverse force when working. The two reinforcing brackets play a role in stabilizing and fixing the cylinder machine. The two fans blow air to cool the working first motor and grinding head. When the output end of the cylinder machine drives the disc to move downward, the guide rod is also forced to move downward. The sliding connection between the pulley and the slide groove makes the disc move smoothly, so that the first... The motor remains vertical, and a three-centimeter-thick strong magnet firmly holds the workpiece inside the grinding groove, facilitating subsequent grinding. When the workpiece size is different, the hydraulic press is started, and the output end of the hydraulic press drives the arc-shaped chuck to move. After the arc-shaped chuck contacts the workpiece, the workpiece is locked and fixed again by the combined action of the grinding groove wall and the arc-shaped chuck. Cotton granules prevent the workpiece surface from being scratched during locking and fixing. After the measuring ruler is rotated upright, the arc-shaped chuck is moved to lock the chuck into the clamp, temporarily limiting the measuring ruler to facilitate subsequent measurement of the workpiece grinding degree. After grinding the workpiece, when the measuring ruler is vertical, the slider moves the vernier rod, so that the bottom of the vernier rod contacts the upper surface of the ground workpiece, and then the scale corresponding to the pointer is read.

The grinding groove 4 has a hydraulic hole 13 inside. A rotating shaft 14 is rotatably connected to the outside of the grinding groove 4. A measuring scale 15 is installed on the outside of the grinding groove 4 and is fixedly connected to the rotating shaft 14. After the worker places the workpiece 11 inside the grinding groove 4, the first motor 9 is started. The output end of the first motor 9 drives the grinding head 10 to rotate. Then, the cylinder 7 is started. The output end of the cylinder 7 drives the disc 8 to move downwards, causing the rotating grinding head 10 to rotate and move downwards. After the rotating grinding head 10 contacts the workpiece 11, it begins to grind the workpiece 11. After grinding the workpiece 11, the worker pulls the measuring scale 15, and through the rotating shaft 14, the measuring scale 15 is rotated and then upright. A person directly measures the height of the workpiece 11 after grinding using an upright measuring ruler 15, thereby determining the degree of grinding on the workpiece 11. This operation achieves excellent results in measuring the degree of grinding and the overall grinding effect. A second motor 16 is fixedly connected inside the motor housing 3. A rotating hole 17 is provided inside the motor housing 3, through which the second motor 16 passes and is fixedly connected to the grinding groove 4. When the second motor 16 is started, its output drives the grinding groove 4 to rotate. The rotating grinding groove 4 causes the workpiece 11 placed inside to rotate, ensuring that the surface of the workpiece 11 is evenly ground during grinding. A reinforcing bracket 18 is provided outside the vertical rod 5, with one end of the reinforcing bracket 18 fixedly connected to the top plate 6. The other end of the bracket 18 is fixedly connected to the cylinder 7. When the cylinder 7 is working, it generates a counterforce. The two reinforcing brackets 18 stabilize and fix the cylinder 7. Two fans 19 are fixedly connected to the outside of the disc 8. The two fans 19 blow air to cool the working first motor 9 and grinding head 10. The vertical rod 5 has a sliding groove 20 inside. A guide rod 21 is fixedly connected to the outside of the disc 8. A pulley 22 is set at the bottom of the guide rod 21. The pulley 22 is slidably connected to the sliding groove 20. When the output end of the cylinder 7 drives the disc 8 to move downward, the guide rod 21 is also forced to move downward. The sliding connection between the pulley 22 and the sliding groove 20 makes the disc 8 move smoothly, keeping the first motor 9 in a vertical state.A strong magnet 23, three centimeters thick, is fixedly connected inside the grinding groove 4. This magnet tightly holds the workpiece 11 within the groove, facilitating subsequent grinding. An arc-shaped groove 24 is provided inside the grinding groove 4. A hydraulic press 25 is fixedly connected inside the hydraulic tank 12. The output end of the hydraulic press 25 extends into the hydraulic hole 13 and is fixedly connected to the arc-shaped groove 24. When the workpiece 11 has different dimensions, the hydraulic press 25 is activated. The output end of the hydraulic press 25 drives the arc-shaped groove 24 to move. After the arc-shaped groove 24 contacts the workpiece 11, the combined action of the groove wall of the grinding groove 4 and the arc-shaped groove 24 locks the workpiece 11 in place again. Rubber cotton particles 26 are provided inside the grinding groove 4, with equal spacing between each pair of particles. These particles prevent damage to the workpiece. When part 11 is locked and fixed, the surface of part 11 is polished. An arc-shaped locking post 27 is provided on the outside of the measuring ruler 15, and a clamp 28 is fixedly connected to the outside of the worktable 2. After the measuring ruler 15 is rotated upright, the arc-shaped locking post 27 is moved to lock into the clamp 28, temporarily limiting the measuring ruler 15 to facilitate subsequent measurement of the polishing degree of part 11. The measuring ruler 15 has a vernier groove 29 inside and a vernier rod 30 on the outside. A ball joint 31 is located at the bottom of the vernier rod 30, slidingly connected to the vernier groove 29. A pointer 32 is located on the outside of the ball joint 31. After polishing part 11, when the measuring ruler 15 is vertical, the ball joint 31 slides along the vernier rod 30, bringing the bottom of the vernier rod 30 into contact with the upper surface of the polished part 11. The reading corresponding to the pointer 32 is then taken.

[0037] In this invention, after the worker places the workpiece 11 inside the grinding groove 4, the first motor 9 is started. The first motor 9 begins to work, and its output drives the grinding head 10 to rotate. Then, the cylinder 7 is started, and its output drives the disc 8 to move downwards, causing the rotating grinding head 10 to rotate and move downwards. After the rotating grinding head 10 contacts the workpiece 11, it begins to grind the workpiece 11. After grinding the workpiece 11, the worker pulls the measuring ruler 15, and through the rotating shaft 14, the measuring ruler 15 is rotated and made upright. Then, the worker uses a straight... The vertical measuring ruler 15 directly measures the height of the workpiece 11 after grinding, thereby determining the degree of grinding on the workpiece 11. Through the above operation, the degree of grinding on the workpiece and the grinding effect are well measured. The second motor 16 is started. The output end of the second motor 16 drives the grinding groove 4 to rotate. The rotating grinding groove 4 drives the workpiece 11 placed inside to rotate, so that the surface of the workpiece 11 can be evenly ground during grinding. The cylinder machine 7 generates a reverse force when working. The two reinforcing brackets 18 play a role in stabilizing and fixing the cylinder machine 7. The two fans 19 provide power to the first working... The motor 9 and grinding head 10 are cooled by air blowing. When the output end of the cylinder 7 drives the disc 8 downward, the guide rod 21 is also forced downward. The disc 8 moves smoothly through the sliding connection between the pulley 22 and the groove 20, keeping the first motor 9 in a vertical position. The three-centimeter-thick strong magnet 23 firmly attracts the workpiece 11 into the grinding groove 4, facilitating subsequent grinding of the workpiece 11. When the size of the workpiece 11 is different, the hydraulic press 25 is started. The output end of the hydraulic press 25 drives the arc-shaped groove 24 to move. After the arc-shaped groove 24 contacts the workpiece 11, it passes through the groove of the grinding groove 4. The combined action of the wall and the arc-shaped groove 24 locks the workpiece 11 in place again. The cotton granules 26 prevent the surface of the workpiece 11 from being scratched when locking it in place. After rotating the measuring ruler 15 to stand upright, the arc-shaped locking pin 27 is moved to lock the arc-shaped locking pin 27 into the clamp 28, temporarily limiting the measuring ruler 15 to facilitate subsequent measurement of the degree of grinding of the workpiece 11. After grinding the workpiece 11, when the measuring ruler 15 is vertical, the slider 31 slides with the vernier rod 30, so that the bottom of the vernier rod 30 contacts the upper surface of the ground workpiece 11, and then the scale corresponding to the pointer 32 is read.
